How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the support weight of the scissors as well as the integrity of the steel cross sections over the length. The scissor structures weight and length are corollaries, meaning that the former determines the latter for a stable scissor jack. An extreme example of this to illustrate the point will be a 20-foot lift length that is featherweight made from Styrofoam that is practically weightless. It definitely would not be able to support at much of a height and could not support a lot at all.
In order to calculate scissor lift length, determine how high in the air you need to support a platform which will support of the weight of the occupants and objects on the platform in addition to the weight of the platform.
To be able to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections which would be necessary to be extended at their full extension. Lastly, you will never want to ascend a few employees up on a platform with their materials which is on a platform supported by any kind of unstable structure since clearly any kind of machinery which is prone to tipping would really put individuals in a really dangerous situation.
Determine the weight of every scissor cross-section. This is very important to determining the weight and length of the scissor lift you will require as well as the overall stability of the machine. When completely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
